Sorry, I haven't had time to experiment lately, so I'm short on progress.

I tried something today - I dd'ed the first 32MB from my recording stick to a 32MB SD card I had laying around, in hopes that the filesystem would be tricked to work (go beyond the disk limit). On a linux laptop I am unable to mount the truncated filesystem:

I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on http://ctrlv.it/ Otherwise "NO HELP"!!!If you want root DISABLE internet access to your device!!!!DO NOT EVER INSTALL FIRMWARE UPGRADE !!!!

So, truncating an ext4 filesystem will not work. This means that lying about USB capacity will not work. I'll do a couple more tests with disks of a lower capacity and see if the TV complains (much) about them.

1. A 32MB SD card formatted ext4 and having an identical filesystem to a working stick (the same files, the same permissions, the same UUID) - is not seen as a PVR device. When I try to record anything it says it needs to format a PVR device and displays only the root device. The SD card is not seen in the OSD, but it's mounted correctly and I can see it via ssh. Most likely PVR devices need to have a minimum size.

2. I took a 2GB stick and formatted it in the TV as a PVR device. I did a small recording. Used SSH, deleted the CONTENTS folder and created a symlink to my NFS share. (Before I copied CONTENTS/NewBoard.ss to my CONTENTS folder on the NFS share). Recording to network share worked correctly.

3. I tried to use the 2GB stick with the dd'ed filesystem from my 8GB PVR device. The TV complained that the filesystem was corrupt and offered to fix it. However it showed disk capacity as 0kb, and it didn't manage to fix anything.

I will try with a 1GB stick, but I expect it to work...

I'm trying to set this for ages.
Can you at least publish here your scripts, to see how you setup this.
I only managed to start NFS on this way https://forum.samygo.tv/viewtopic.php?f ... =10#p50147
Script is started without error, but it won't record anything, some warning about not enough free space

Sorry I haven't had time to publish anything because I haven't had time to write the scripts. But here are instructions to do it manually:
1. You must prepare and dedicate a USB stick larger than 2GB for media recording. Format it in the TV and record something as a test. Disks lower than 2GB are not supported by the TV (it complains it's too small), unfortunately. I'm sure somebody like zoelechat can remove that limit. Reboot the TV after doing a recording.
2. Set up your NFS share as usual (edit /mnt/etc/init.d/03_03_nfsmount.init) and make sure you can access those shares from the TV (e.g. play a video from a share). Prepare a directory or a share where you want to save your recordings
3. Log in via telnet/ssh into your TV and identify which is your mount point for the recording stick. You should see two directories CONTENTS and lost+found under a directory in /dtv/usb. Run the command below to find it:

5. Assuming that the target where you want to record to is located at this path: /dtv/usb/sdc/nfs/192.168.1.5/TVRecordings/CONTENTS, and that this path exists you will need to create a symlink from your recording stick to this new directory

Sorry guys, it's been too long. I kept putting this off, but now I created a startup script that should move your recordings from USB to a network share and set up the symlink as needed.
You need to edit it and set your network recording path (example inside). The code is here: https://github.com/mad-ady/samygo-network-recording, patches and feedback welcome.

You need to edit the file and set the correct path to your share (here is a nfs example, but you can use samba as well):
